Arctic Marine Acoustics and Oceanography.
Abstract
A research camp was maintained continuously on Fletcher's Ice Island (T-3) in the Arctic Ocean from May, 1962, until September, 1974. During those 12 years a scientific party from Lamont maintained a program of geophysical data collection on the ice island as it drifted with wind and currents over a 14,000 km track in the Beaufort Sea. The location of the ice island was determined by celestial navigation using a theodolite up until 1967 when a satellite navigation was installed. Ocean depth was measured with a 12 k Hz echo sounder continuously during the drift except for minor gaps due to equipment failures. Gravity was read several times each day with a LaCoste and Romberg gravimeter. The total magnetic field was measured with a proton precession magnetometer and recorded continuously except for some gaps due to instrument problems. These data constitute a valuable resource for studies of ice drift and of crustal structure in the Beaufort Sea.
